BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to liquid crystal displays, and more particularlyto liquid crystal displays wherein resistance differences caused byelectrode link length differences are substantially eliminated.

2. Description of the Related Art

Generally, a liquid crystal display (LCD) controls light transmissivityusing electric fields to display a picture corresponding to videosignals. To this end, the LCD includes a liquid crystal display panelhaving liquid crystal cells arranged in a matrix, and driving circuitryfor driving the liquid crystal display panel.

In a liquid crystal display panel, gate lines and data lines arearranged such that they cross each other. The liquid crystal cells arelocated in the areas defined by the crossing lines. The liquid crystaldisplay panel includes pixel electrodes and a common electrode forapplying electric fields to the liquid crystal cells. Each pixelelectrode is connected, via source and drain electrodes of a switchingthin film transistor, to a data line. The gate electrode of theswitching thin film transistor is connected a gate line. By selectivelyapplying appropriate signals to the various data and gate lines, adesired pixel voltage signal can be applied to each pixel electrode.

The driving circuitry includes gate drivers for driving the gate lines,data drivers for driving the data lines, and a common voltage generatorfor driving the common electrode. The gate drivers sequentially applyscanning signals (or gate signals) to the gate lines, which causes a rowof thin film transistors with gates connected to a particular gate lineto be driven. The data drivers sequentially apply data voltage signalsto data lines, which causes a column of thin film transistors havingelectrodes connected to a particular data line to be driven. The commonvoltage generator applies a common voltage signal to the commonelectrode. Accordingly, the liquid crystal element driven by both ascanning signal and a data voltage signal is enabled. An electric fieldis then applied between the pixel electrode of that liquid crystalelement and the common electrode, causing the light transmissivity tochange in accordance with the data voltage signal, causing a pixel to bedisplayed.

The driving circuitry usually takes the form of chips that are mountedon tape carrier packages (TCP) of a tape automated bonding (TAB) system.The TCPs connect to electrode pads provided on a liquid crystal displaypanel. The electrode pads in turn connect via electrode links to signallines at a pixel area. Thus, the driving circuitry electrically connectsto the signal lines at a pixel area.

In an LCD, as the number of pixels increase to form a high-res olutionpicture, the available conductor width and conductor spacing becomesvery small. Furthermore, a high integrated density of driving circuitsin a PDA (Personal Digital Assistant) employing a small liquid crystaldevice of below 6 inch enforces the pad spacing to be very small. As aconsequence and as shown in FIG. 1, the electrode links between theelectrode pads and the signal lines at the pixel area have lengths thatvary in accordance with their positions. Since conductor resistancedepends on conductor length, the electrode links have resistance thatvary in accord with position.

FIG. 1 also shows an electrode arrangement of a gate pad-link portion ina conventional LCD. In FIG. 1, a gate pad 12 connected to a gate drivingcircuit (not shown) is provided at an edge portion of a lower substrate10. The gate pad 12 applies a driving signal from the gate drivingcircuit, via a gate link GK, to a gate line GL that is arranged at apixel area.

The gate pad 12 has a structure as shown in FIG. 2 and in FIG. 3. Thegate pad 12 includes a gate pattern 16 formed on a substrate 26, a gateinsulating film 22, and a protective film 24. The gate pattern, gateinsulating film, and protective film are sequentially disposed on thesubstrate 26. An opening in the gate insulating film 22 and protectivefilm 24 exposes a pad area of the gate pattern 16. A transparentelectrode pattern 18 is in contact with the exposed gate pattern 16.That transparent electrode pattern 18 is also in electrical contact withthe TCP having the driving circuit via a contact portion 20, shown inFIG. 2.

Turning back to FIG. 1, the gate links GK have lengths that depend ontheir positions, whereas they have the same width and thickness.Accordingly, the resistances of adjacent gate links GK only have a smalldifference. However, a large resistive difference exists between the ‘A’portion, where the gate link lengths are relatively small, and the ‘B’portion, where the gate link lengths are relatively large. As a result,the gate signals applied to the gate lines GL are distorted, causingpicture quality deterioration.

Similarly, the data links between the data pads and the data electrodesalso have a resistive difference according to the wire length. Thisresistive difference causes a distortion of the data signals applied tothe data lines, which causes picture quality deterioration.

Therefore, a display having little or no differences in the resistancesof gate links and/or of data links would be beneficial.

DETAILED DESCRIPTION OF THE ILLUSTRATED EMBODIMENT

Referring now to FIG. 4A and FIG. 4B, there is shown a pad 40, which canbe a data pad or a gate pad, according to the principles of the presentinvention. The pad 40 is connected to an electrode link 23 having arelatively long length. As can be seen from FIG. 4A, the length of atransparent electrode 28 overlapping and in contact with a pattern 16 islengthened over the prior art by a length Lpxl1 the extends in the pixelarea direction. As the unit area contact resistance between the pattern16 and the transparent electrode 28 is relatively high, lengthening thetransparent electrode 28 by the length tpxl1 increases the contact area,reduces the contact resistance, and compensates for the relatively highresistance of the relatively long electrode link 23.

The pad shown in FIG. 4B is connected to an electrode link 25 having arelatively small length. As can be seen from FIG. 4B, the length of thetransparent electrode 30 is lengthened by a distance Lpxl2, which isless than the distance Lpxl1. Lengthening the transparent electrode 30by Lpxl2 increases the contact area somewhat, correspondingly reducesthe contact resistance, and compensates for the resistance of theelectrode link 25 having a relatively small length.

An additional length of the pad, that is, the transparent electrodepatterns 28 or 30 compensates for a resistance difference according tothe length of the electrode link to make a signal wire having anequivalent resistance determined by the following formula:Lpx 1=(Ravg×Tpx 1×Wpx 1)/ρpx 1

Where Lpx1 represents an additional length of the transparent electrodepattern 28 or 30, Ravg represents an average resistance of the link,Tpx1 represents the thickness of the transparent electrode pattern (28or 30), Wpx1 represents a width of the transparent electrode pattern 28or 30, and ρ represents a non-resistance value of the transparentelectrode pattern 28 or 30.

If the transparent electrode pattern 28 or 30 is formed on a basis of anadditional length Lpxl1 or Lpxl2 of the transparent electrode pattern 28or 30 of the pad determined by the above formula, then it is possible tocompensate for a resistance difference according to the length of theelectrode link 23 or 25, thereby forming signal conductors having thesame resistance. The large resistance of a long electrode link 23 can becompensated by increasing the length of the transparent electrodepattern 28 in the pixel direction by a relatively large length. On theother hand, the small resistance value of a short electrode link 25 canbe compensating by only slightly increasing the length of thetransparent electrode pattern 30. The sectional structure of a padportion having the transparent electrode pattern 28 or 30 is as shown inFIG. 3. The transparent electrode pattern 28 or 30 contacts a padportion (not shown), which is provided to a TCP (Tape Carrier Package)loaded with a driving circuit, through the contact area 20, as shown inFIGS. 4A and 4B.

Again, the electrode pad structure described above can be used tocompensate for resistance differences in both data links and gatelengths.

FIGS. 5A and 5B show a pad 50 according to a second embodiment of thepresent invention. The pad 50 is connected to an electrode link 53having a relatively long length. As can be seen from FIG. 5A, the lengthof an electrode pad 52 being in contact with a transparent electrode 56is enlarged by Lpad1 in the pixel area direction. This aims tocompensate for a relatively large resistance value loaded on arelatively long electrode link 53, and enlarges an length of theelectrode pad 52 to reduce a large resistance value of the pad portion50. The transparent electrode 56 is in contact with a pad portion (notshown), which is provided to a TCP (Tape Carrier Package) loaded with adriving circuit, through the contact area 54.

The pad 50 shown in FIG. 5B is connected to an electrode link 55 havinga relatively small length. As can be seen from FIG. 5B, the length ofthe electrode pad 58 is enlarged by a distance Lpad2, which is less thanthe distance Lpad1. Lengthening the electrode pad 58 by Lpad2 reducesthe resistance, and compensates for resistance of the electrode link 55having a relatively small length. The transparent electrode 56 is incontact with a pad portion (not shown), which is provided to a TCP (TapeCarrier Package) loaded with a driving circuit, through the contact area54 as shown in FIGS. 5A and 5B.

An additional length of the electrode pad 52 or 58, that is, theelectrode pad pattern 52 or 58 compensates for a resistance differenceaccording to the length of the electrode link 53 or 55 to make a signalwire having an equivalent resistance.

If the electrode pad pattern 52 or 58 is formed on a basis of anadditional length Lpad1 or Lpad2 of the electrode pad pattern 52 or 58of the pad portion 50, then it is possible to compensate for aresistance difference according to the length of the electrode link,thereby forming signal conductors having the same resistance. The largeresistance of a long electrode link can be compensated by increasing thelength of the electrode pad pattern 52 in pixel direction by arelatively large length. On the other hand, the small resistance valueof a short electrode link can be compensating by only slightlyincreasing the length of the electrode pad pattern 58.

Referring to FIGS. 6A and 6B, there is illustrated a pad 60 according toa second embodiment of the present invention. The pad 60 is connected toan electrode link 63 having a relatively long length. As can be seenfrom FIG. 6A, the width of a transparent electrode 66 being in contactwith an electrode pad 62 is enlarged by Wpxl1. This aims to compensatefor a relatively large resistance value loaded on a relatively longelectrode link 63, and enlarges an width of the transparent electrode 66to reduce a large resistance value of the pad 60. The transparentelectrode 66 is in contact with a pad portion (not shown), which isprovided to a TCP (Tape Carrier Package) loaded with a driving circuit,through the contact area 64.

The pad 60 shown in FIG. 6B is connected to a electrode link 65 having arelatively small length. As can be seen from FIG. 6B, the width of thetransparent electrode 68 is enlarged by a width Wpxl2, which is lessthan the distance Wpxl1. Enlarging the transparent electrode 68 by Wpxl2reduces the resistance of the pad 60, and compensates for resistance ofthe electrode link 65 having a relatively small length. The transparentelectrode 68 is in contact with a pad portion (not shown), which isprovided to a TCP (Tape Carrier Package) loaded with a driving circuit,through the contact area 64.

An additional width of the transparent electrode 66 or 68, that is, thetransparent electrode pattern 66 or 68 compensates for a resistancedifference according to the length of the electrode link 63 or 65 tomake a signal wire having an equivalent resistance.

If the transparent electrode pattern 66 or 68 is formed on a basis of anadditional width Wpxl1 or Wpxl2 of the transparent electrode pattern 66or 68 of the pad 60, then it is possible to compensate for a resistancedifference according to the length of the electrode link, therebyforming signal conductors having the same resistance. The largeresistance of a long electrode link can be compensated by increasing thewidth of the transparent electrode pattern 66 by a relatively largewidth. On the other hand, the small resistance value of a shortelectrode link 65 can be compensated by only slightly increasing thewidth of the transparent electrode pattern 68.

FIGS. 7A and 7B show a pad 70 according to a fourth embodiment of thepresent invention. The pad 70 is connected to an electrode link 73having a relatively long length. As can be seen from FIG. 7A, the widthof an electrode pad 72 being in contact with a transparent electrode 76is enlarged to have a width of Wpad1. This aims to compensate for arelatively large resistance value loaded on a relatively long electrodelink 73, and enlarges a width of the electrode pad 72 to reduce a largeresistance value of the pad 70. The transparent electrode 76 is incontact with a pad portion (not shown), which is provided to a TCP (TapeCarrier Package) loaded with a driving circuit, through the contact area74.

The pad 70 shown in FIG. 7B is connected to an electrode link 75 havinga relatively small length. As can be seen from FIG. 7B, the electrodepad 78 becomes small in a width Wpad2 which is less than the widthWpad1. Controlling the width of the electrode pad 78 in a value of Wpad2reduces the resistance, and compensates for resistance of the electrodelink 75 having a relatively small length. The transparent electrode 76is in contact with a pad portion (not shown), which is provided to a TCP(Tape Carrier Package) loaded with a driving circuit, through thecontact area 74.

A controlled width of the electrode pad 72 or 78, that is, the electrodepad pattern 72 or 78 compensates for a resistance difference accordingto the length of the electrode link 73 or 75 to make a signal wirehaving an equivalent resistance.

If the electrode pad pattern 72 or 78 is formed on a basis of acontrolled width Wpad1 or Wpad2 of the electrode pad pattern 72 or 78 ofthe pad 70, then it is possible to compensate for a resistancedifference according to the length of the electrode link 73 or 78,thereby forming signal conductors having the same resistance. The largeresistance of a long electrode link can be compensated by increasing thewidth of the electrode pad pattern 72 by a relatively large length. Ohthe other hand, the small resistance value of a short electrode link canbe compensating by only slightly increasing or decreasing the width ofthe electrode pad pattern 78.

Referring to FIGS. 8A and 8B show a pad 80 according to a fifthembodiment of the present invention. The pad 80 is connected to anelectrode link 83 having a relatively long length. As can be seen fromFIG. 8A, an electrode pad 82 being in contact with a transparentelectrode 86 is formed by a conductive material having a relatively lownon-resistivity (or conductivity) ρ1. This aims to compensate for arelatively large resistance value loaded on a relatively long electrodelink 83, and reduce a large resistance value of the pad portion 80. Thetransparent electrode 86 is in contact with a pad portion (not shown),which is provided to a TCP (Tape Carrier Package) loaded with a drivingcircuit, through the contact area 84. Furthermore, in the case of thatthe transparent electrode 86 is formed by a transparent material havinga relatively low non-resistivity ρ1, the relatively large resistancevalue loaded on the relatively long electrode link 83 can becompensated.

The pad 80 shown in FIG. 8B is connected to an electrode link 85 havinga relatively short length. As can be seen from FIG. 8B, a electrode pad88 is formed by a conductive material having a non-resistivity ρ2, whichis higher than the non-resistivity ρ1. Selecting the electrode padmaterial 88 having the non-resistivity ρ2 reduces the resistance andcompensates for resistance of the electrode link 85 having a relativelysmall length. The transparent electrode 86 is in contact with a padportion (not shown), which is provided to a TCP (Tape Carrier Package)loaded with a driving circuit, through the contact area 84. On the otherhand, if the transparent electrode 86 is formed a transparent materialhaving the non-resistivity ρ2, the relatively small resistance valueloaded on the relatively short electrode link 85 can be compensated.

The selective non-resistivity of electrode pad 82 or 88, that is, theelectrode pad material 82 or 88 compensates for a resistance differenceaccording to the length of the electrode link 83 or 85 to make a signalwire having an equivalent resistance.

If the electrode pad pattern 82 or 88 is formed on a basis of aselective non-resistivity ρ1 or ρ2, then it is possible to compensatefor a resistance difference according to the length of the electrodelink 83 or 85, thereby forming signal conductors having the sameresistance. The large resistance of a long electrode link can becompensated by forming the electrode pad pattern 82 by a relatively lownon-resistivity of conductive material. On the other hand, the smallresistance value of a short electrode link can be compensating by onlyslightly forming the electrode pad pattern 88 by a slightly lownon-resistivity of conductive material.

Referring to FIGS. 9A and 9B, there is shown an electrode link 93 and 95according to a first embodiment of the present invention. In FIG. 9A,the electrode link 93 being connected to an electrode pad 92 included ina pad 90 has a relatively long length. The electrode link 93 is formedto have a width Wlink1 wider than that of the prior art. This aims tocompensate for a relatively large resistance value loaded on arelatively long electrode link 93, and reduce a large resistance valueof the pad link 93. The transparent electrode 96 is in contact with apad portion (not shown), which is provided to a TCP (Tape CarrierPackage) loaded with a driving circuit, through the contact area 94.

The pad link 95 shown in FIG. 9B being connected to the electrode pad 92has a relatively short length. As can be seen from FIG. 9B, a electrodelink 85 is formed to have a width which is less than the width Wlink1.Controlling the width of the electrode link 95 in the Wlink2 reduces theresistance and compensates for the resistance of the electrode link 95having a relatively short length.

The controlled width of the electrode link 95, that is, the electrodelink pattern 93 or 95 compensates for a resistance difference accordingto the length of the electrode link 93 or 95 to make a signal wirehaving an equivalent resistance.

If the electrode link pattern 93 or 95 is formed on a basis of acontrolled width Wlink1 or Wlink2, then it is possible to compensate fora resistance difference according to the length of the electrode link 93or 95, thereby forming signal conductors having the same resistance. Thelarge resistance of a long electrode link can be compensated by formingthe electrode link pattern 93 in a relatively wide width Wlink1. On theother hand, the small resistance value of a short electrode link can becompensating by only forming the electrode link pattern 95 in a slightlywide width Wlink2.

FIGS. 10A and 10B shows a link 101, which is connected to a pad 100,according to an embodiment of the present invention. The pad 100includes a transparent electrode 106 connected to a pad portion (notshown) provided to a TCP through a contact area 104. The link 101includes a electrode link 103 and 105 connected to a electrode pad 102of the pad 100 and a compensating pattern 107 and 109 installed to theelectrode link 103 and 105.

The electrode link 103 shown in FIG. 10A has a relatively long length,while the electrode link 105 of FIG. 10B is formed in a relatively shortlength. The compensating pattern 107 of FIG. 10A is formed longer thanthe compensating pattern 109 of FIG. 10B in a length.

The long compensating pattern 107 reduces a relatively large resistanceload on the electrode link 103 having the relatively long length.Meanwhile, the short compensating pattern 109 increases a relativelysmall resistance of the electrode link 105 having the relatively shortlength. Controlling the compensating pattern 107 or 109 in the lengthcompensates for a resistance different according to the length of theelectrode link 103 or 105 to making a signal wire having an equivalentresistance.

If the compensating pattern 107 or 109 is formed on basis of an lengthof the electrode link 103 or 105, then is possible to compensate for aresistance difference according to the length of the electrode link 103or 105. The large resistance of a long electrode link can be compensatedby forming the compensating pattern 107 in a relatively long length. Onthe other hand, the small resistance value of a short electrode link canbe compensated by only forming the compensating pattern 109 in aslightly short length.

The compensating pattern can be formed on a basis of a length of theelectrode link to have a varied thickness or a varied width. In thiscase, The varied thickness or width of the compensating patterncompensates for a resistance different according to the length of theelectrode link 103 or 105 to making a signal wire having an equivalentresistance.

In addition, the compensating pattern can be formed in a constant size.The compensating pattern is loaded on the electrode link 103 or 105 atleast one. A number of the compensating pattern loaded on the electrodelink 103 or 105 is determined according to a length of the electrodelink 103 or 105. The number of the compensating pattern loaded on theelectrode link 103 or 105 compensates for a resistance differenceaccording to the length of the electrode link 103 or 105 to make asignal wire having an equivalent resistance.

Furthermore, the compensating pattern can be formed by a conductivematerial different according to a length of the electrode link 103 or105. The conductive material different according to the length of theelectrode link 103 or 105 compensates for a resistance differenceaccording to the length of the electrode link 103 or 105 to make asignal wire having an equivalent resistance.

As described above, according to the present invention, the length ornon-resistivity of the transparent electrode pattern or the electrodepad pattern included in the pad is differentiated to compensate aresistance difference according to the length of the electrode link, sothat it becomes possible to make the electrode pad-link having anequivalent resistance.

The size (including the width and/or thickness) of the electrode linkpattern can be differentiated to compensate a resistance differenceaccording to the length of the electrode link, so that it becomespossible to make the electrode pad-link having an equivalent resistance.

Furthermore, the number or the non-resistivity of the compensatingpattern loaded on the electrode link pattern can be differentiated tocompensate a resistance difference according to the length of theelectrode link, so that it becomes possible to make the electrodepad-link having an equivalent resistance.

Furthermore, the same initial bias voltage is applied to thecorresponding signal lines owing to the electrode pad-link having thesame resistance, so that it becomes possible to prevent picture qualitydeterioration resulting from a signal distortion caused by a resistancedifference between the electrode links in the prior art.

Although the present invention has been explained by the embodimentsshown in the drawings described above, it should be understood to theordinary skilled person in the art that the invention is not limited tothe embodiments, but rather that various changes or modificationsthereof are possible without departing from the spirit of the invention.Accordingly, the scope of the invention shall be determined only by theappended claims and their equivalents.
